Back at Mack's house,
Mack kept looking at the runes on the device in his hand, even being the case that he nano bots in his eyes showed the name and purpose of each rune, it was just that, without the actual rune circuit those runes were nothing, he would need to crack the precise way to use those runes inside a rune circuit so they could show its effects.
Mack had already tried a few common rune circuits he thought that may apply to the situation, but they didn't work in the end.
"What a banger, to know the runes and not be able to use them," said Mack, throwing the device at the table and reclining his back in the chair.
Mack put his hands behind his neck and looked up at the ceiling, thinking about what to do, but no clear ideas came to his mind. The only thing that remained was 'try and error' and Mack hated that.
